Dyewaste effluent samples were collected from textile dyeing unit as well as CETP located in Tirupur. Strains having decolorizing ability of various textile reactive dyes were obtained from primary and secondary screening methods. Stenotrophomonas maltophilia RSV-2 strain could degrade the mixed dyes up to 2100 ppm with in 67 hrs and 58 % decolorization was obtained through acclimatization study. The strain was identified based on biochemical and 16S ribosomal RNA gene sequence study. Optimization of yeast extract composition, pH, temperature, salinity and biomass composition was determined. Decolorization performance of individual dyes using two different substrates was also studied.
